The only switch for the power windows system (master switch) is mounted in the center console and controls the drivers and passenger windows. A permanent magnet motor moves each power window up and down. The direction the motor turns depends on the polarity of the supply voltage. The master switch controls the supply voltage polarity. With the ignition switch in the ON position, voltage is applied to a Power Windows Circuit, 30-amp fuse in the fuse panel.
